Why copper nails? Copper is naturally antimicrobial and rust-free. In Eastern wellness traditions, copper is associated with grounding, energy flow, and self-purification — adding a meaningful dimension to your Sadhu practice beyond the physical benefits.

How to practice: Start with socks for a gentler feel and gradually progress to barefoot. The 10mm spacing provides a genuine challenge — ideal for practitioners ready to step beyond the basics. Begin with just a few seconds and increase your time day by day. Just 1 minute on the Sadhu Board equals walking 2.6 miles barefoot — activating acupressure points, improving circulation, and sharpening mental focus.

Each board features a unique wood grain and texture — no two boards are identical. Two interlocking boards fit neatly into the textile case for safe storage and travel. Free worldwide shipping.
